Specification of Letters Patent.

Patented Nov. 11, 1913.

Application filed May 18,1912. Serial No. 698,209;

To all whom it may concern Be it known that 1, WILLIAM S. Vnrrnn, a citizen of the United States, residing at in the county of New York and State of New York, have invented certain new and useful Improvements in Case- Making Machines, of which the following is j a full, clear, and exact specification.

lhis invention relates to case making machines, and is particularly directed to case making machines capable of ready adaptability for varying the width of the back-lining strip of book covers, and also for securing economy in the amount ofpaper-board or other material used in making up book covers.

More specifically, this invention is directed to improvements in case making machines whereby a continuous strip of paper or like material of the width of the desired back-lining strip is fed by suitable mechanism in proper relation to be picked up by the suction cup and automatically cut the desired length, which mechanism is preferably adjustable to adapt the same to varyng widths of backs of the cases to be pro duced. By meansfof my invention, the paper or like material is fed as a continuous strip through guides of a novel construction, usually supported by the inside bars of the cover board feeding mechanism, and suitable mechanism provided for simultaneously adjusting the said inside bars and guides.

By my invention the necessity of employing trimming knives is obviated and great economy in the amount of paper used in making the case or coveris effected as well as increasing materially. the output of the case making machine. 7

Other features and advantages of my in vention will be readily understood from the following description, and the accompanying drawings, in which-- Figure 1 is a perspective of a case making machine embodying my invention; Fig. 2 is a detail sectional view taken on the line 2-2 of Fig. 1 ;'Fig.3 is an enlarged detail showing my adjustable guides in perspect ve; and Fig. 4 isadetail sectional view of the knife and rolls for guiding the strip of back lining paper therethrough.

Referring to the drawings, Fig. 1 represents the end portion of the Smyth type I of case-making machine at which the magazlnes for the cover boards are posltioned. In this type of machine, as shown In Jacobs United States Patent No. 580,111, dated April 6, 1897, the boards are fed one at a time by suitable apparatus from the bottom of each of two of the magazines, the two boards thus fed being moved along two pairs of parallel, mutually adjustable guide-bars to a point where the two boards and the back-lining strip, disposed intermediate of the same, are picked. up by a suction-cup, and placed on adhesive-coated-buckram, linen or other suitable covering, and then piled up at one end of the machine. When the size of the covers is varied, the magazines are adjusted to accommodate the different size of the side-boards, and the two pairs of adjustable guide-bars are correspondingly varied, that is, the distance between the bars of each pair, and the distance between the inside bars of the two pairs. The supportingv frame for the magazines and the adjustable guide-bars is indicated in Fig. 1 and comprises the end members 1, 2 connected by the transverse members 3, 1. The uprights of one magazine are indicated at 5, 6; the other magazine is formed of the inner upright 7 and the outer upright 8, the latter being largely broken away in order to show other parts of the device more clearly. The outside bar 9 and the inside bar 10, provided respectively with ledges 11, 12 facing one another, form one pair of guide-bars for feeding cover-boards for one side of the covers. The inside bar 13 and the outside bar 14, similarly provided with oppositely facing ledges, forms the other pair of guidebars for feeding cover side of the covers. In order to secure the proper feeding of the c0ver-boards, the in side guide-bars are provided respectively with springs 10, 13 (see also Fig. 2), whereby the cover boards are yieldably held in position against the outside guide-bars. In this typeof case-making machines, suitable adjusting means is provided, described more fully hereinafter, whereby for less width of cover, the bars of each pair of guide-bars are moved closer together, and for greater widths of cover, the guide bars of each pair are moved farther apart; when the thickness of the boards for the other books is increased or decreased, the distance between the inside guide-bars is correspondingly increased or decreased.

The paper or like material to be supplied to the machine for forming the back-lining of the case is fed, in accordance with my inv ntion, as continuous strip 15 from the roll 16 rotatably mounted in the brackets 17, the continuous strip 15 having the width of the back-lining of the case. The strip 15 is fed over the roller 18 below the bar 3,

thence between the flanges 19, 20 of the opi pcsitely disposed guides 21, 22, thence between the slots 23, 2at-of the guides 21, 22, and under the bar l, between the rollers 25, (see Fig. 4') between the blades of the knife 26, and finally on a level with the ledges 11 and 12. The rollers 25 are driven by gears 35 intermittently to feed the proper length for the back-lining strip. Thus the movement of the strip 15 on the top of the table of the machine is in a direction opposite to the direction in which the boards from the two magazines are fed. As shown, the guide 21 is mounted on the bar 10, and the guide 22 is mounted on the bar 13, said bars being adjustable relative to one another by suitable regulating mechanisn. shown one form of such regulating mechanism in Fig. 1, comprising the right and lefthand screws 27, 28 connected together through the shaft 29 and suitable gearing, and regulated by the crank 30. The outside bars 9, 14 are also mounted adjustable on the cross-bars 3, t, and may be provided with separate screw shafts and crank, if desired.

The adjustable guides 21, 22 are shown as having forward slots 19, 20 formed of a lower flange 81 and an upper adjustable flange 32, and extensions projecting toward the rear of the machine, and at or near their rear ends are provided with slots 33. By reason of the forward slots 19, 20 being connected to the rear slots 33 by extensions somewhat resilient, but having sufficient stiffness to take up the slack of the strip 15, in cooperation with the rollers by which said strip 15 is fed to the top of the machine, improved results of marked value are secured. hen it is desired to vary the width of the back-lining strip, the crank 30 is turned to move the bars 10, 13 the desired distance apart, and at the same time securing adjustment of the guides 21, 22 with respect to one another. It will be noted that each guide 21,

22 is formed of angled forward portions so arranged with respect to one another that the guiding flanges 31, 32 project inwardly from the bars v10, 13 to provide a proper clearance at the top of the bars 10, 13 to allow the suction cup to transfer the backlining. strip to the adhesive coated case-covering, as will be understood. where the dimensions of the back-lining strip are frequently varied, a number of I have F or such use rolls 16 carrying different widths of strips are so arranged that the desired roll can be moved in alineinent with the roller 18 and guides 21, 22, or the roll of desired width of strip substituted in the bracket 17, 17.

By this invention, the usual cutting knives are done away with, and also the disadvan tages incident to adjusting such cutting knives and sharpening the same are ob viated, as well as avoiding delays due to loosening of the usual rubber washers and to frequent replacing such parts due to wear. Besides, the inconvenience and difliculties due to the heaping ofthe cut-off edges of paper are overcome, and economy in the amount of paper used effected.

It will be understood that changes or modifications in the 7 specific arrangement illustrated may be made without departing from this invention.

Having thus described my invent-ion, I declare that what I claim as new and desire to secure by Letters Patent, is
